Please note that all 3 games tested here are made by miHoYo / HoYoverse. They have got kernel level anti-cheat so that the game executables run in administrator permission. Would it be possible that since Mudfish runs in user permission, it cannot see admin processes? (Although tasklist in user permission do list these processes...)

I think your syntax isn't correct. At least you can't put the same process name multiple times so the following rules aren't going to work:

• P:YuanShen.exe;47.116.0.0/16
• P:YuanShen.exe;N47.116.0.0/16
• P:YuanShen.exe

You need to optimize this and make one line rule. However before going further, first please make sure that WFP Item mode is working fine on your Windows 11 23H2.

Please check How to check the basic functionality using WFP Item Mode link and test whether it's good for you or not.

Yes I have tried single process name like this and they do not work.

P:YuanShen.exe

/

P:YuanShen.exe
P:StarRail.exe
P:ZenlessZoneZero.exe

/

P:YuanShen.exe,StarRail.exe,ZenlessZoneZero.exe

I have also tried WFP item mode with P:xxx.exe and it does not work.

Full VPN mode with WFP mode turned on also does not work. However, Full VPN mode alone worked.

:-( If How to check the basic functionality using WFP Item Mode link doesn't work for your case, I think it's more related to WFP Item mode... So `P:` option doesn't work on your system.

If possible, please send us Problem Report. I need to check the internal logs to confirm that there's a problem on WFP Item mode or not.

I have submitted a problem report through Mudfish Launcher. There is also a screen recording showing all the actions performed during logging.
